Warnings and watches are based on a "time to impact" factor. If you are outside that time envelope, they won't issue the watch/warning yet even if you might be effected. They will wait undtil the proper time to issue it. If I remember, I think warnings are 48 hour lead time, but I might be wrong. Don't quote me! - plus I think she's already closer than 48 hours...about 36-42 hours until south of eastern FL, 48 hours until off the tip of southern Florida. If there is a northward change in the models, that's less than 48 hours.
Also, they may have mentioned the change in the warnings becuase of the center reformation north...which might affect model runs.

Actually RC, I think the strict definition is 36 hours announcement for a Watch and 24 hours for a Warning. In this case, they went early to evalcuate the FL Keys.
